ALMA CO(2-1) Gas Dynamics in NGC 315: A Multi-Method Benchmark for Supermassive Black Hole Mass Measurement
Dieu D. Nguyen, Benjamin D. Boizelle, Hai N. Ngo +11
We present ALMA Cycle~7 \cotwo\ observations of the circumnuclear disk in NGC~315 at an angular resolution of $0\farcs230\times0\farcs175$, improving on past measurements and resol…
Dynamical Evidence for a Billion Solar Mass Black Hole in Galaxy NGC 4061 from ALMA CO(2-1) Kinematics
Dieu D. Nguyen, Long Q. T. Nguyen, Elena Gallo +6
We present the first robust dynamical measurement of the supermassive black hole (SMBH) mass in the massive early-type galaxy NGC 4061 using high-spatial-resolution ALMA observatio…
Extending the Frontier of Spatially-Resolved Supermassive Black Hole Mass Measurements to at : Simulations with ELT/MICADO High-Resolution Mass Models and HARMONI Integral-Field Stellar Kinematics
Dieu D. Nguyen, Michele Cappellari, Tinh Q. T. Le +8
Current spatially resolved kinematic measurements of supermassive black hole (SMBH) masses are largely confined to the local Universe (distances Mpc). We investigate…
Simulating intermediate black hole mass measurements for a sample of galaxies with nuclear star clusters using ELT/HARMONI high spatial resolution integral-field stellar kinematics
Dieu D. Nguyen, Michele Cappellari, Hai N. Ngo +8
Understanding the demographics of intermediate-mass black holes (IMBHs, M) in low-mass galaxies is key to constraining black hole seed format…
